摘要

隔热材料延长了食品的保质期，降低了能源消耗。聚氨酯（PU）保温材料通常用于保持食物的冷热。在食品和制药行业，提高PU的隔热性能可以显著有助于节能和降低食品相关成本。在聚氨酯泡沫中加入膨胀石墨（EG），通过热压得到聚氨酯/膨胀石墨（PU/EG）复合材料。通过傅立叶变换红外光谱（FTIR）、扫描电子显微镜（SEM）和热重分析（TGA）对含0.05%、5%和10%EG的复合材料进行了表征。

Production and characterization of polyurethane/expanded graphite composites for industrial food preservation

Thermal insulation materials extend the shelf life of food and reduce energy consumption. Polyurethane (PU) insulation materials are often used to keep food hot and cold. Improving the thermal insulation properties of PU can significantly contribute to energy savings and lower food-related costs in the food and pharmaceutical industries. Polyurethane/expanded graphite (PU/EG) composites were obtained by hot-pressing by adding expanded graphite (EG) to PU foams. Composites with 0.05%, 5%, and 10% EG were characterized by Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM), and thermogravimetric analysis (TGA).
